Leners Patent No. 92,190, dated .my c, 1869.-

IMPRovEMENT IN SELF-CLOSING (rocas` ron wernmcziosnms.

The Schedule referred to in these Letters Patent vand making ofthe same.

To all whom it may concern-.-

Be it known that I, 'CHARLES HARRISON, of the city and State of New York, have invented and made anv Improvement in Cocks for Water-Closets; and I doI hereby declare -the following to be Aa full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is a vertical section and Figure 2 is a sectional plan of the same, at the line il! 5E.

Similar marks of reference denote the sameparts.

Closet-cocks have heretofore been made with va variable water-chamber, to control the closing of a valve, and allow the water to run a given length of time. There has, however, been dificulty in regulating these cocksto suit the varying pressures of water in diierent places, because, with heavy pressures, the cock closes too rapidly, and does not allow suiicient ow of Water, and with light pressures the water is` wasted.

My invention relates to a cock for water-closets, in which the water-leakage is regulated from the outside ofthe cock, so as to vary the time in which the water is expelled from the'variable chamber, and consequently the quantity of water that' is allowed to ow into the closet. y

` In the drawinga isl the cylinder or'band of the cock, connected to the closet by the arm b, or other suitable means; c

of the said closet-cock,

piston; f, the cap; g, the leather packing; and h, the spring to close the valve; all of the general character heretofore employed'.

lis the inlet-coupling or pipe, and k is the outletcoupling or pipe to theWater-closet.

The cup-leather or piston e allows water to rush .past it when the'valve is pressed down to open the ]ated, to render the dischargeofwater from the cham! ber n more or less rapid, and the closing of the valve is thereby under control, so that it may, be adjusted or varied according 'to the head of water, or according to the amount required' for washing the closet, and this regulation is electedwithout disturbing any ofthe connections or opening the cock, and in case of obstruction'iu the .leakage-pipe i, itcaugenerallybel removed by turning the screw o, but if not, the'screw can be taken out'very easily. 1

What I claim, and desire to secure by Letters Patent, is'

A water-closetcock, in which the leakage-water'- way Ii, between the variablechamber n and the outlet k, is regulated from' outside the cock, as and for the purposes set forth.

In witness whereof, I have hereunto set my. signa'-l turethis 3d day of March, A.A D. 1869.
